2. In an internal combustion engine working on the two-stroke cycle, the combination of a cylinder, a single sleeve within the cylinder open at both ends, a piston within the sleeve having a. longer travel than the sleeve moving in the same direction therewith-during each of its strokes and arriving at the end of each stroke at approximately the same time as the sleeve, and inlet and exhaust ports in the cylinder and in the sleeve.

3. In an internal combustion engine working on the two stroke cycle, a cylinder, a single sleeve within the cylinder and open at both ends, a piston within the sleeve, an inlet port at one end of the sleeve, an exhaust port at the other end, an inlet port at one end of the cylinder, an exhaust port at the other end of the cylinder, an enlarge-- ment of the cylinder, and a piston upon the sleeve working in the' enlargement and compressing air therein.

4. In an internal combustion engine working on the two stroke cycle, a cylinder open at one end, a sin le cylindrical sleeve fitting within the cylin er open at both ends, inlet ports at the open end of the cylinder and exhaust ports at the closed end, ports at the two ends of the sleeve at the same distance apart as the inlet and the outlet ports in the cylinder, a piston fitting within the sleeve, a crank shaft opposite the open end of the cylinder, a connecting rod extending from the piston to a crank on the crank shaft, connecting rods extending from the sleeve to cranks or eccentrics on this shaft 50 disposed that the sleeve is moved in phase with the piston but with a shorter travel and that the ports in the sleeve and the ports in the cylinder are closed to one another at the end of its inward stroke but are brought opposite to one another when the piston is at and near the end of its out-ward stroke and travels beyond them.

5, In an internal combustion engine working on the two stroke cycle, a cylinder open at one end, a single cylindrical sleeve fitting within the cylinder open at both ends, inlet ports at the open end of the cylinder and exhaust ports at the closed end, ports at the two ends of the sleeve at the same disjance apart as the inlet and the outlet ports in the cylinder, :1 piston fittin within the sleeve, a crank shaft opposite 51c open end of the cylinder, a connecting rod extending from the piston to a crank on the crank shaft, connecting rods extending from the sleeve to cranks or eccentrics on this shaft so disposed.

that the sleeve is moved in phase with the piston but with a shorter travel and that the ports in the sleeve and the ports in the cylinder areclosed to one'anot er at the end'of its inward stroke but are brought opposite to one another when the piston is at and near the end of its'outward stroke and travels beyond them, an enlargement of the open end of the cylinder, an annular piston on the sleeve working in this enlargement and compressing air therein, a compressed air reser voir into which the inlet ports at the open end of the cylinder open and a valve controlling the delivery of compressed air from the enlargement of the cylinder to the reservoir.

G. In an internal combustion engine working on the two stroke cycle, a cylinder, at single sleeve within'the cylinder and open at both ends, a piston within the sleeve and moving in phase therewith, inlet and exhaust ports in the cylinder and in the sleeve, an enlargement of the cylinder and a piston upon theslceve working in the enlargement and compressing air therein.

7. In an internal combustion engine working on the two stroke cycle, a cylinder, a single sleeve within the cylinder and open at both ends, a piston within the sleeve, and having a longer travel than the sleeve, a crank, a rod connecting the piston to the crank, two eccentrics situated one each side of the crank and connections between the sleeve and the eccentrics.
